Definitions
- the invention relates to a foam body with flame retardant Properties, especially for flame retardant sealing of joints and wall openings in buildings and the like.
- connection joints When erecting all types of structures, both connection joints, Wall and ceiling joints as well as butt joints.
- the Joint widths range from a few millimeters to 150 mm and are often simply sealed with mortar. Farther there are wall openings, e.g. for pipelines and the like must be closed.
- Fire protection cords such as disclosed in GB-A-2 181 093, DE-A-3 735 779 or DE-U-87 15 428.5, so-called joint sealing options Fire protection cords, fire protection tapes or strips foamed polymers (mainly PU-based) based on work in different ways. Common to all is that they contain intumescent substances or mixtures that the Seal the joint against smoke and fire penetration. As intumescent raw materials come from expanded graphites, mixtures Melamine / pentaerythritol / ammonium polyphosphate or water glass (Na silicate solutions).
- the invention has for its object a foam body specify that realizes a fire-resistant joint material and the very easy to process, i.e. fast and easy is to be assembled, and the everyday functions (e.g. sound and Thermal protection, watertightness) of a sealing material Fulfills.
- the joint flanks should be mineral, as well as metallic substrates.
- the foam body according to the invention essentially consists made of a PU foam as the core, with an aqueous impregnation is impregnated, the impregnation preferably consisting of inorganic Fillers and fire retardants, preferably on Phosphate-based. It preferably serves as the binder an aqueous acrylic dispersion.
- the impregnation also allows the foam after its Compression, slowly rising with later application and fill the joint completely.
- SK film Foam core laminated self-adhesive film
- the PU foam chars and forms stable foam structure made of smoke and fire spread delayed by the joint in adjacent fire sections.
- special requirements e.g. extremely wide joints or at the Application on metallic substrates can lead to liability between Joint flank and SK film / PU foam due to softening or Shrinkage is lost.
- the SK film fire protection i.e. intumescent, equipped.
- an intumescent material such as expanded graphite
- a double-sided adhesive tape for example made of polyethylene, polyester (corresponds to SK film), so that a uniform coating is produced.
- the amount of graphite can be between 10 and 150 g / m 2 .
- boric acid or its salts can be added in smaller amounts (5-10%) during the production of the film. Borates give off endothermic water, which lowers the fire temperature, and finally melt into a glass-like substance, so that the expanded material, such as graphite, does not fall apart so easily.
- water glass sodium silicates
- boric acid sodium silicates
- vermiculites vermiculites and combinations of melamine / pentaerythritol / ammonium polyphosphate or their derivatives are suitable.
- the impregnated PU foam is covered with this composite film laminated on both sides (glued).
- the small composite film thickness of approx. 0.4 mm in the example is the amount of intumescent material expanding in the event of fire, e.g. of the graphite, out to any column that may appear and to close cracks in the charred PU foam.
- the expansion volume Expandable graphite is around 30 to 40 times its own Output volume (about 3-5 mm per layer in the embodiment).
- this foam body with a much wider range of applications than just as Jointing material that can be made available. Due to the good flexible properties it is possible to use the foam body to wrap, e.g. to electrical cables or pipes with it wrap. Metallic substrates are not a problem because no melting due to the very small softening range of the PU foam can be observed.
- Another field of application is molded parts made of the foam body, especially fire protection plugs that are temporary and permanent partitioning of wall openings not yet occupied or bushings can be used.
- the stoppers are simply punched out of a flat material, for example.
- Fire protection pillows are usually included Mineral wool and / or a more or less intumescent Material filled glass fiber bags.
- Commercially available fire protection pillows are only slightly elastic and compressible mainly used for larger wall breakthroughs.
- the embodiment The invention for this application provides packaging of a foam body according to the invention in a glass fiber fabric before, so that a direct flame attack on the PU foam prevented and the erosion of the same is delayed. Due to the elastic properties of the PU foam is a Adapt to the surface of the external environment (cables, masonry) very possible.
- FIG. 1 shows the structure of a flame-retardant composite film V, consisting essentially of two self-adhesive films (2) and one expanded graphite layer (1) enclosed between them.
- Cover material (3) for example a silicone paper, the is in each case applied to the outside of the self-adhesive films (2), prevents unwanted sticking during winding and storage the composite film V.
- the illustration is not to scale, but is only meant to be represent the basic structure.
- the total thickness of the composite film V is approximately 0.4 mm.
- FIG. 2 shows a possible embodiment of a foam body S with a foam core (4) on both sides is provided with an arrangement according to FIG. 1, but on the the foam core (4) adjacent sides of the composite films the silicone papers (3) already when creating the foam body S have been removed using the composite foils V to glue the foam core (4).
- the silicone papers Before installing the Foam body S in a building joint, as in the drawing shown, at least one of the silicone papers still present be removed from the flame-retardant foam body S, around this at least on one side with the flank W of Walls 5 limited building joints to glue and thereby to secure its place. This state is shown in Fig. 2.
- the silicone paper 3 could also the other side of the foam body S are removed.
- An application with two external ones would also be conceivable Silicone papers. Such is an installation after an unwanted decompression of the PU foam possible because of the smooth silicone paper the introduction easier.
- FIG. 3a shows the use of a foam body according to the invention S as a plug in an opening in a wall 5.
- Fig. 3b shows the arrangement of Fig. 3a in longitudinal section. Accordingly, there are two plugs in a row in the wall opening, if necessary at a mutual distance, and the plugs each consist of a first, inner foam core 4a, which in the above Type is soaked, a composite film according to FIG. 1 (without 3) by the reference numerals 1, 2 of their Ingredients marked on each side of the inner foam core 4a, and glued to the composite films second, outer foam core 4b, also in the above Kind of soaked.
- the composite films are transverse to the extension of the wall breakthrough, i.e. in the event of fire across the Flame, in contrast to the application according to Fig. 2, where the composite films run in the direction of the flame
- Mineral wool may be in the space between the two plugs be installed.
- FIGS. 3a and 3b The use as a stopper according to FIGS. 3a and 3b is different Requirements than those for joints according to Fig. 2.
- a multiple arrangement is the solution to these problems the composite film, e.g. shown in Fig. 3b, cheap.
- These composite films prevent water from penetrating, as well as fire and smoke passage.
- As a safety reserve can apply a thin layer of a fire-resistant Sealant to be applied to the component reveal.
- 4a and 4b show an alternative to the punched fire protection plug 3a and 3b the spiral winding of a relatively thin, strip-shaped foam body of the invention kind of creating a stopper to fill out of a wall breakthrough (hole) of sufficient diameter. Since the soaked foam core 4 still after application If something opens, smaller gussets close by themselves. Larger gaps should be sealed with a sealant. 4a and 4b speak for themselves and therefore need not be explained further.
- Figure 5 shows the wound embodiment for use for cable or pipe penetrations.
- a cable 6 can be seen or pipe into a wall breakthrough by a strip trained foam body according to the invention wrapped is.
- the innermost self-adhesive layer in the wrap provides the mechanical hold on the cable or tube securely while the outermost Layer ensures a hold on the masonry and when inflating of the intumescent material causes sealing functions there.
- FIG. 6 Another use of the foam body according to the invention shows Figure 6. It is conceivable that the bilateral with composite film V coated foam core 4 as a filling for fire protection pillows can serve.
- the glass fiber fabric prevents rapid burn-off as it Separates fire / smoke from the foam body S.
- This variant has two essential fire protection pillows Benefits.
- the pillow is dimensionally stable and very good manageable and secondly it is compressible and can do something else intumesce.
- Figures 7 and 8 show the application as a thermal insulation material for all types of cable and pipe penetrations is in front of and behind an existing partitioning device 8 at least the underground of the partitioning device to be protected once represented by the foam body according to the invention with the reference numerals 1, 2, 4 of its components.
- the purpose is that subsequent measures for an extension of the fire resistance period or the function maintenance can be hit.
- An application as a flame barrier on cable routes 10 is according to the 7a and 7b also possible.
- Such flame arresters are supposed to Prevent cables from continuing to burn on cable trays.
- the the underlying idea is that by sheathing the cables 6 the oxygen supply is cut off, so that the fire goes out.
- the composite film preferably with expanded graphite as intumescent material in it, touches the cables 6. Outside but should be avoided on the composite film, at least if it contains expanded graphite, because it is better burns as the soaked foam core.
